Hey LW
Well ... here I am again, imagine that
. I'd just like to expand a mite on what Galen posted as well as Jake C. Oh, and Me too.
Galen posted he had never, 1n 50 years, seen a Cap Gun that was reliable out of the box. I concur. Mostly. A.). It only has to run for 6 rounds. Then you're going to throw it and run. No one ever tried to reload a Cap Gun during a fight and lived to tell how it went. So some "out of the box" guns just might work.
Jake C. cites the most common "fix's" to start getting Cap Gun ready to play CAS with. A perfectly good idea. A smooth running, easy to run (OEM's ain't easy) CAS ready Cap Gun is my choice too.
Then you have the other qualifier for "daily carry." If we be talking about Uberti, you only have two choices for barrel length. 7&1/2 inches and 8 inches. Lotta barrel to stuff down yer britches and draw in a panic (you WILL be in a panic). At least with Pietta you have a choice of barrel length, right down to a 3 inch Snubbie (Perfect for CCW)
Since this requirement is going to primarily be aimed at "Social" work, which is normally also "close" work, long barrels are a hinderance. Up close and Personal, a fully loaded .36 or .44 will probably fully penetrate the average human. All you need. .36 and .44 will both do the job but I personally am a believer in "Bigger IS Better" when shooting bullets into people. Besides, even if you don't hit em, the Blast, Fame and smoke is going to scare the bejesus out of anyone. Almost as good as hit em (not really).
And let nobody regress into throwing thoughts of the comparison of Suppository Shooters into the discussion. We be talking Cap Guns here.
